No one asked you to have them. The Pentagon stated in 2013 that there are "around" 5000 bases total, with "around" 600 of them overseas...

January 24, 2018 ; the United States has approximately 800 formal military bases in 80 countries, a number that could exceed 1,000 if you count troops stationed at embassies and missions and so-called “lily-pond” bases, with some 138,000 soldiers stationed around the globe...

But that's up to the American tax payers, not the EU etc.

The EU need their own NATO, not paying you lot for your war missions...
